Dynamic molecular motions resulting from the folding of a flexible macrocyclic component in a Cu(I)-complexed pseudorotaxane have been evidenced by variable temperature NMR experiments. The proposed conformational changes are also supported by the X-ray crystal structures of the compounds and computational studies.
通过变温 NMR 实验证实了在 Cu(I)-配合的类轮烷中柔性大环组件折叠所产生的动态分子运动。所提出的构象变化也得到了化合物的 X 射线晶体结构和计算研究的支持。
